New Delhi: CBI in connection with the 2G spectrum allocation scam questioned two top executives of Tata Group- Chairman of the group's realty and infrastructure arm R Krishna Kumar and its Managing Director and Chief Executive Officer Sanjay G Ubale here on Thursday.

The two officials of Tata Realty and Infrastructure were questioned regarding the alleged Rs 1,600 crore loans extended to Unitech to procure 2G spectrum.

This was the second time that Ubale has been quizzed by the CBI in connection with the firm's alleged linkages with Unitech, one of the two companies which have been mentioned in the FIR filed by the agency on October 21, 2009.

The CBI had earlier questioned Sanjay Chandra of Unitech on issues relating to offloading of majority stake to Norway based company Telenor after getting 2G spectrum license.

CBI is probing whether Tata Real Estate had paid Rs 1,600 crore to Unitech for a land deal at a time when the real estate company was applying for 2G license in 2007.

The Unitech Managing Director was asked to explain about offloading of shares during the questioning, CBI sources said.

According to the CBI’s FIR, Unitech has allegedly offloaded over 60 per cent of its stake to Telenor and earned a profit of 267 per cent even before the service roll-out.

The FIR read, "M/s Unitech was allotted UAS licences for 22 circles for Rs 1658 crore. It offloaded its 60 per cent of shares in the licences to Telenor of Norway for Rs 6100 crore even before the roll-out."
